I hate seeing all these posts about new 680 this or 690 that being released by so and so.....hello....they still aren't available! I hate it though because at work we have boxes of both the 680s and 690s. And when I say boxes I mean big boxes that they come in OEM style with like 30 in a box! Luckily for me, I can buy them from my company at a 3% - 5% wholesale markup! Muhahahahahahahaha.......I work for a custom computer company.
